<u>Question</u> 4 : 770 mm Hg = how many pascals

<u>C</u><u>onversion from mm Hg to atm</u> :

  • 760 mm Hg = 1 atm

  • 1 mm Hg = 1 / 760 atm

  • 770 mm Hg = (1 / 760) × 770 atm

  • 770 mm Hg = 1.013 atm

<u>Conversion from atm to kPa</u> :

  • 1 atm = 1.013 × 10² kPa

  • 1.013 atm = 1.013 × 1.013 × 10² kPa

  • 1.013 atm = 1.026 × 10² kPa

<u>Conversion of kPa to Pa</u> :

  • 1.013 atm = 1.026 × 10² × 10³ Pa

  • 1.013 atm = 1.026 × 10⁵ pascals

hence, 770 mm Hg = 1.026 × 10⁵ Pa

The change in the internal energy of a system that releases 2,500 j of heat and that does 7,655 j of work on the surroundings is
g100num [7]

We are given that the system “releases” heat of 2,500 J, and that it “does work on the surroundings” by 7,655 J.

The highlighted words releases and does work on the surroundings all refers to that it is the system itself which expends energy to do those things. Therefore the action of releasing heat and doing work has both magnitudes of negative value. Therefore:

heat released = - 2, 500 J

work done = - 7, 655 J

Which means that the total internal energy change of the system is:

change in internal energy = heat released + work

<span>change in internal energy = - 2, 500 J +  - 7, 655 J</span>

<span>change in internal energy = -10,155 J</span>

B) initial speed (u)=3
final speed (v)=8
time (t)= 10
acceleration (a)=?

v=u+at
8=3+a(10)
5=10a
a=1/2= 0.5 m/s²

c)displacement (s)=?
1st section of journey

v ²=u ²+2as
8 ²=3 ²+2(0.5)s
64=9+1s
s=55meters

2nd section of journey
a=0
t=7
u=8
s=?

s=ut+1/2at²
s=8(7)+1/2(0)(7 ²)
s=56 meters

56+55= 111 meters

(For graph x axis =time (sec) & y axis= velocity (m/s))
